lines -in.Fig. 171' Tl'icseducts are-givenany suitable shape, size, and curvature to enable theinto eifect this result. The-casing. 3 is also provided with a, eyl-ind-rical bo're-3' concentric with its. axis,'. in. which is. a. disk 8 which just fits said bore. The. disk. 8 is shownni-detaill-lin 19,20 and-21, and comprises two disks, 8,- end :8. The-.disk. 8 contains a. centrally located square hole'9, whichis adaptedto-receive a...valve.ste m, as will appear below, and the disk 8! is provided with symmetrically located recesses 10-, ll, 12 and 13, whichare ada ted to registerwi-th the ducts 4", 6?, 5 and 7 respectively, when the disk 8 is in. place. Thefrecesses 1G and 13 are united by a slot 14 endthe recesses 11 and 12 are similarly-united by aslot 15.

Although I have shown and described the disk 8 as being formed of two disksS and 8 y which are iixedtogether, it is obvious that if I andl, shown (hagraini desired, the disk 8 may be formed by one integral piece. However, it is fer-able to form it of two pieces, as shown, ecause then, as indicated inFig. 2.0, the siotsll i and'15 may be concealed. The arrangements of respleictively', and left topointsin the-casing.

slots and recesses above described in the disk 8 enable the ducts 4 and 6 to be connected when the disk 8 is in one position, and the ducts and 7 b to be similarly connected at duct 7 b and similarly the duct 6 is connected with the duct 5. By turning the disk through a second angle'of 90 degrees, the

ducts are connected as first above described,

so that by rotating the disk 8 in the same .direction to angles of 90 degrees, the supply pipe 6 is alternately connected with the reservoirs 1 and 2, and at the same time, the other reservoir not connected withthe supply'pipe 6, is connected to the drain pipe 7.

To the casing 3 is secured the flanged bracket or tube 16, whose end is reduced to fit in the bore 3, and its shoulder 17 rests against and is flush with the end of the casing 3, as shown in Fig. 18. The tube 16 has an annular shoulder 18 rojecting into its interior, and its outer on is slightly reduced and screwthreaded to receive a cap 20, which secures a bushing 21 around a shaft 22. A packing 23 rests against the shaft 22 between the bushing 21 and the shoulder 18, so as to forin'a tight joint. A coiled spring 24 encircles the shaft 22, and one end of it rests against the shoulder 18, and the other end rests on the disk 8 whereby the disk is held to its seat to form a tight joint. The bracket 16 is fixed to the casing 3 by means of screws 25, or it may be held in any suitable manner, and to the bracket 43 in a manner described below.

The free end of the shaft 22 is provided with a pawl and ratchet mechanism and a sector which will now be described. The ratchet 26 is fired to the shaft 22 by means of a collar 27 and a set screw 28, or in any other suitable Way. This ratchet 26 is rovided with four equi-distant teeth 26 w ich are engaged by a pawl 29 pivoted to a bolt 30 fixed in the segment 31. A coiled spring 32 encircles the bolt 30, and has one end fixed to the sector 31, and the other end rests on the pawl 29, thereby forcing it into engagement with the teeth on the ratchet 26. The sector 31 is mounted on the shaft 22, so as to be free to oscillate thereon without loss of motion, and is provided with teeth 33 which engage a rack 34, as indicated in Figs. 1, 2 and 4. A pin 35 is secured in the sector31 and is geared with the universal link 36 which is articulated at 37 and 38, and pivotally connected at its other end with an arm 39 which is fixed to the spindle 40 of an indicator 41. indicator 41 indicates, as shown in Fig. 1, by numerals in the dial 42, the number of times the sector 31 is oscillated by the movement of the rack 34, as described below. From the foregoing, it is evident that when moved in one direction, the sector 31 through the This { pawl 29 and ratchet 26 rotates the shaft 22 i and when moved in the other direction, the

i shaft is not rotated and the pawl 29 slides free on the ratchet 26.

The casing 3 is su ported by the bracket 43 through the bracket 16 which is bolted thereto and this bracket 43 is shown somewhat in detail in Fig. 16. This bracket 43 supports a bearing 44 in which the end of the shaft 22 is journaled and held in its correct osition by means of a collar 45, which is fixed thereto. The indicator 4] is also moun ted on this bracket 43, and held in position by screws 46, and the bracket 43 is, in turn, supported by bolts 47 on a plate 48, i which also sup orts the entire vending mechanism. This liiacket 43 on its up er edge is provided with a screw 43 with a arge head which forms an adjustable stop that engages a pin 31 fired in the sector 31 and limits its movement in one direction.

Near its lower end the plate 48 is provided with a suitable nozzle 49 which is connected by a union 50 with the discharge ipe 7 in the usual manner. The nozzle 49 is urtherreinforced by a large nut 51 which rests against the rear of the plate 48, thereby clamping it between this nut 51 and a shoulder 52 on the nozzle. In the plate 48 and above the nozzle '49is' a bushing 53 which is provided with a shoulder 54 which rests against the outside of the plate 48 and isprovided with a reduced and screw-threaded inner endwhich engages a nut 55 which is screwed against the inner surface of the late 48. As shownin' Figs. 1 and 7, the bus 'n'g 53 is somewhat prolonged between the screw-threaded portion 56 and is recessed-at 57 for purposes which will appear below.

As shown in Fig. 1, the bushing 53 does not extend far enough to interfere with the action of the sector 26. 'Slidably mounted 1 in the bushing 53 and snugly fitti'm the same is a second bushing 58. The bushing 58 is slotted at 59 and 60, as shown in Figs. 12 and 13, and is recessed at 61 for urposes which will appear below. The bus 'ng 58 is filled by two plugs 62 and 63 which are preferably rovided with a registering and cylindrical ore 65. This bore 65 is so shaped as to slidingly mount and support the cylindrical end 66 of the rack 34. The extreme end 67 of the rack 34 is considerably reduced in diam eter for a reason which will ap ear below. The end 68 of the plug 63 is ma e into suitable form which may be easily and readily han 1c is provided with stops 69 against which the bushing 58 abuts and which is also adapted to abut against the end of the bush ing 53. Both the plug 63 and the plug 62 are provided with a bore 70 which is considerably smaller than the bore-'65, and at one l side thereof, and in which slides the eylin l drical shaft 71 which is provided with an gras ed by the hand of the operator and this plugs 62 and 63 and their com onent enlarged head 72 which is adapted to im inge against a sto 73 when in the osition s own in Fig. 5, an against a secont stop 74 which is fixed to the bracket 43, when the mechanism is in the position shown in Fig. 6. The

portion 7 5 of the cylindrical shaft 71 is considerably reduced, and is so placed as not to be opposite the coin receiving slot 7 6, when the mechanism is in the position shown in Fig. 5, and to be opposite this coin receiving slot when the mechanism is in the position shown in Fig. 2. The plug 62 is provided with set screws 77, access to which is had through slots 60 and this plug is cut away so as to be flush with the curved portion of the bushing 58, as indicated at 78 in Fig. 2'. The outer end of the plug 62'is corrugated at 79 on its coin receiving surface, as is the inner end 80 of the plug 63, and the 1plug 63 18 pro- 20' vided with projections 81 whic abut a ainst the plug 62 whereby a coin receiving slot 82 is formed, which is flush with the slot 59 in the bushin 58, and forms therewith the coin receiving s ot 76.

If desired, the corrugations 79 and 80 may be omitted, and the device will operate, but not as well as with the corrugations, for the reason that if a moist coin is dropped into a slot without corrugations, it is very apt to become stuck and lodged. Where the corrugations are present, there is no surface to which the coin may become attached. The end 67 of the rack 34 is reduced so that if a washer is inserted in lieu of a coin, the reduced end 67 will protrude through the hole in the washer and not operate the mechanism, thereby preventing a fraudulent use of the device.

From the foregoing, the operation of my improved mechanism will be readily understood. Assuming the parts to be in the position indicated in Fig. 1, a coin is inserted through the slot 59 in the bushing 58, and falls between the plugs 62 and 63; the plunger 84. being composed of the. bushing 58 and arts. The plunger 84' is then shove inwar ly by means of the handle 68 and the end 67 of the rack 34 rests a ainst the coin, as indicated in Fig. 6. The plunger 84 then forces the rack inwardly to the position shown in Figs. 2 and 6 and the coin in its initial position is shown in Fig. 9,.and is prevented from slippin through the-plunger 84 by the cylindrical bar 71. 'When the plug reaches the inner limit of its movement which terminates when the shoulder 69 rests against the bushing 53, the head 72 im inges against the stop 7 4, thereby forcing t 1e reduced portion 75 opposite the coin receiving slot. Meanwhile the rack 34 oscillates the sector 31 through the inter-meshing teeth 33 thereby rotating the ratchet 26 and shaft 22 through the pawl 29. At the sametime, through the crank pin 35 and universal link 36, the a'rn'i the reservoir holds only a limited amount of liquid, the flow is terminated when the reservoir is emptied, so that only a definite and pre-determined amount of liquid can flow through the apparatus after one movement of the plunger. When the plunger is drawn outwardly, the screws 77 permit a slight movement of the plunger before the rack 34 is moved, whereby the coin is released and falls through the slot 57 into a coin receptacle which is not shown, and then the screws 77 engage the enlarged part 66 of the rack 34, and cause the rack to be drawn outwardly with the plunger, whereby the sector 31 is turned in the opposite direction through'an angle of degrees, but this time it does not rotate the shaft '22, because the pawl 29 simply slides over the ratchet 26. The outward movement of the plug 84 is terminated by the pin 31 which impinges against a proi'ection 43 on the su port 43, and an enarged portion of the s raft 71 is brought opposite the coin receiving slot 58 in the plunger 84 by the projection 73 from the bushing 53 which projections enga e against the enlarged head 72 on the shaft 71. The ap aratus is then in the position indicated in ig. 1, and ready to receive another coin, after which the same cycle of operations may be re eated.

rom the foregoing, it is apparent that a very simple and automatic vending device has been disclosed. As this device may be modified in many ways without departing from the spirit of my invention or sacrificing any of its advantages, I do not re ard it as Having thus described my invention, what a I' claim is 1. In a liquid dispensing apparatus, a hollow piston and a rack sliding in said hollow piston and guided thereby, a coin receiving means with walls, and corrugations in the walls of said means which prevent the coin from sticking thereto.

2. In a liquid dispensing apparatus, a hollow piston, a rack sliding therein, means with walls in said hollow piston adapted to receive the coin, a reci rocating rod passing through the edges of t 1e walls of said means, and means for causing said rod to reciprocate so that a coin is released by the reciprocation of said rod.
